Start search & inverse search

[Hagoromo]

Hi,

I'm newbie in awk ;-)

I have a text file with 150000 records (lines), and
I need to start the search of a pattern in line 60000.
It's possible to do that?

Another question, I can make a inverse search (i.e.,
search a pattern from line 50000 to line 40000)?

Thanks in advance

I need to start the search of a pattern in line 60000
awk '/pattern/ && NR>=60000{print}' /path/to/input

Hope This Helps, PH.

No, [tt]awk[/tt] does not have full file handling features. It can advance through the file only by reading line after line.

But why your problem needs that solution ? Why not simply search from record 40000 to 50000 and display the last ( or latest ) matches ?
